Question

A car is traveling at a speed of 20m/s and has a mass of 1200kg how much kinetic energy does it have

Answer 1

Answer:

Explanation:

The formula for Kinetic Energy is

$KE=\frac{1}{2}mv^2$. Filling in:

$KE=\frac{1}{2}(1200)(20)^2$ It looks like we only need 1 significant digit here but I'll give you 2 and you can round how you want.

KE = 2.4 × 10⁵ J
